AUTOMATIC INTEGBATOR.

Speciflcationcf Letters Patent.

Application filed January 29, 1909. Serial-No. 475,039.

To all whom-it may concern:

Be it known that I, FRANK E. PENDLETON,

a citizen of the United States, and a resident of Montclair, Essexcounty, and State of My invention relates to improvements in automaticintegrators and consists of novel features and parts and combinations,the objects of which are fully set forth hereinafter. I

Referring to the drawings accompanying and forming part of thisapplication, in

which the same reference character indicates the same part in theseveral views, F igure 1 is a section on line 1 of Fig. 2. Fig. 2 1s asection on line 2 of'Fig. 1. Fig. 3 is a detail view. Fig. 4 is a toprplitl mview.

t The part marked A is a frame supporting toe clock mechanism B, havingdouble spimgs C.

10 1s a disk connected to the shaft 11 of the clock mechanism and ad tedto be rotated thereb in the direction of the arrow, at the rate of onecomplete revolution per hour.

12 is a post 'to which is pivotally secured one end of the bridge 13.This end of the bridge has a downwardly projecting arm 14 which rest ontop of a bracket 18, formin a part of the standard 19 which supports tis end of the bridge. l

I Secured to the arm 16, of the bridge isa counter registering device"20. Pivotally mounted between the arms 14 and 16 of the bridge andarallel to the face of the disk 10, is a sha' t 21. One end of thisshaft is connected to the counter 20 by any suitable means, such as theconnection shown at 22, and rotates the said counter mechanism. Securedon this shaft is a" wheel 23 which contacts with the outer face of thedisk 10 and normally bears against the center thereof. The shaft isprovided with aiflat surface 24 and the contact wheel is provided with acorresponding. fiat portion 25 co -acting therewith, which revents thewheel from rotating butpermits free longitudinal movement on said shaft.1

26 is an arm secured to the bridge. Pivoted to this arm is a lever 27One end of which the following is a specithis lever carries the weight28 which is adjustable in the arm and is secured in posiwater meter, toa governor of a speed motoror to similar devices. On this rock shaft isan arm 32. The freeend of this arm is con nected to the contact wheel 23and moves the said contact wheel therewith. The free end of this arm isconnected to a pointer 33 which moves in front of the scale 34 securedto the bridge 13. v

35 is a lever pivoted on the shaft 36. One arm 35 of this lever isconnected to the arm 32. In the construction shown in the drawing thefree end is bifurcated and straddles the pointer 33 connected to thesaid arm 32.

The other arm35 of this lever carries a three hours each, and also ruledor divided into concentric circles 37 fifteen one hundredths of an inchapart. Th's chart is car .ried by the disk 38 pivoted at 39. Theperipher of the disk is provided with teeth 40. l\ eshing with theseteeth is a pinion 41 which is connected to a shaft 42 driven by clockmechanism through thegears 43 and 44, these gears being of such numberand so proportioned that the disk- 38 will travel in the samedirectionas the disk 10, as indicated by the arrow thereon, and will make onecomplete rotation in eight days.

D is a casing inclosing the mechanism. The pivots or shafts 36 and 42are so connected that they maybe separated to permit the casing to beremoved.

Patented Mar. 21, 1911.

Said casing is provided with openings E, F and G covered by transparentmaterial so that the counters 20, the chart 37 and the scale 34 ,may beread without removing the casing.

The mechanism described is for use where the variable is a function oftime,

such as speed, horse power, fiowof fluid in cubic feet per unit of time,flow of electric current in amperes per unit of time, etc. The positionof the contact wheel 23 when opposite the center .of the disk 10 is tocorrespond with zerospeed, horse power, flow, etc. Equal movements ofthe contact wheel from the center, toward the right as shown in theapparatus illustrated, are to be proportional to equal measurements ofspeed, horse power, flow, etc. Thus the arm 32 when swung to the rightso that the distance of the contact wheel 23 from the center of the diskwill be proportional; for example, to the cubic feet of water flowingper hour through a valve, the movement of which produces the rockingmovement of the shaft 31 which causes the arm 32 to swing to the right.

The operation of the apparatus is as follows: With the parts in theposition shown in the drawing -and the clock mechanism running, therotation of the disk 10 produces no movementof the contact wheel 23, andof course, there is no movement of the counter mechanism 20. If thecontact wheel 23, however, is moved to the right by the swinging of thelever 32, caused by the increase of the flow of water, or the increasein horse power, or the increase in flow of electric current, it will berotated by the disk 10 and the speed of rotation will correspond to thedistance from the center of the disk, and this speed will be transmittedto the shaft 21 and will be indicated on the counter 20. If the contactwheel 23 having unit radius, is moved to the right unit distancecorresponding to unit speed, and if disk 10 completes one revolution inunit time, then the counter 20 shows unit distance passed over. If thecontact wheel 23 is moved a distance of two units from the center of thedisk 10 and remains there during unit time, then the counter will showtwo units of distance passed over, etc., and if the contact wheel 23remains at such distance from the center of the disk two units of timethen the counter will show 4 units of distance passed over or theproductions of units of speed and units of time. In like manner, at allintermediate positions of the contact wheel 23 the counter continuallyshows the prod-' net of all the increments of distance. When the arm 32is swung to the right, the arm 35 of the lever 35 being in contacttherewith causes the other arm 35 of the lever to move to the lefttoward the center of the chart 37 and the pencil carried by that armwill indicate momentarily the speed, horse power, flow, etc. As thischart is moved in the direction .of the arrow at a uniform speed theinward and outward movement of the pencil over the chart caused by thedifference in the speed, horse power, flow, etc., will mark a curve tobe traced on the chart which shows a graphic record of the relativespeed, horse power, flow, etc., throughout the day or even a week, thechart being intended to be changed weekly. The mechanism is such thatthe disk 10 and contact wheel 23 are in close contact at all times, andthis is accomplished by the lever and weight 27 and 28. -As this leveris pivoted to the arm 26 and the roller 30 carried by said arm isbearing against the inner surface of the disk 10, which acts as afulcrum at that point, the weight P throws the free end of the bridge13, which carries the contact wheel 23, toward the disk 10 and thusmaintains at all times contact between said disk and wheel. The pressureof the disk and contact wheel may be varied by adjusting the position ofthe weight 28 carried by the lever 27. Moving the weight closer to thelever causes less pressure, and extending it farther of course causesgreater pressure. The rolling contact 17 of the bridge on the bracket 18causes the weight to freely pull the bridge toward the disk 10. In orderto swing the bridge away from the disk when it is desirable to do so forany purpose, the scale 34 is removed from the bridge; then the arm 32and the arm 35* can be disconnected and moved out of the way, whereuponthe bridge can be freely moved or swung upon the post 12 away from thedisk.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention could be madewithout departing from the scope thereof, I intend that, all mattercontained in the above description or shown in the accom anying drawingsshall be interpreted as illustrative and not in a limitin sense.
